You might have got away with it if you had a APS-C body (480mm FF equivalent FoV), but 300mm on a FF really is going to be VERY limiting.

It's more about pixel density than sensor size, when you get into focal-length-limited scenarios. The 3.1MP D30 should come to mind whenever one is tempted to talk about APS-C magnification powers.

Well yes, obviously.

Most current APS-C cameras have a higher pixel density than a 26Mp RP.

So without getting too technical (ie. actual pixel sizes etc) a 300mm lens on an average current model (around 24Mp to 32Mp) APS-C (with a FF equivalent FoV of 480mm) is barely acceptable for birding (a 32Mp 90D or M6 ii might be OK), and a 26Mp FF is definitely going to be very limiting. That was the only point I was making.
